Once subscribed the SSL web service, and after validation by our team, you will receive an access key to the email address used during payment.
To use this key, simply add the request var k=<YOUR_KEY> to all requests to the SSL web service located at https://ssl.geoplugin.net/

For example, to call the JSON web service with an IP address to look up, with the fictitious key Fqw9ch1k6Han28xP you would for the request as such:

https://ssl.geoplugin.net/json.gp?k=Fqw9ch1k6Han28xP&ip=xx.xx.xx.xx

or using jQuery:

https://ssl.geoplugin.net/json.gp?k=Fqw9ch1k6Han28xP

Note the above key is fictitious and will not work.
The format of the requests is identical to all the other web services.
